The present application claims priority to U.S. Provisional ApplicationNo. 62/794,306, filed on Jan. 18, 2019, and titled “MEDICATION TRACKINGSYSTEM,” the entirety of which is incorporated by reference herein.

TECHNICAL FIELD

The subject matter described herein relates generally to thedispensation of pharmaceuticals and more specifically to a trackingsystem for the delivery of medication.

BACKGROUND

Patient-controlled analgesia pumps may provide patients direct controlover the delivery of some medications including, for example, opioidpain medications, which are otherwise administered in single doses bymedical professionals via intramuscular injections or intravenousinjections. A patient-controlled analgesia pump is a computerized pumpthat houses a reservoir containing multiple doses of a medication and isconnected directly to a patient's vein. The patient-controlled analgesiapump may be configured to deliver a constant flow of the medication tothe patient. Alternatively and/or additionally, the patient-controlledanalgesia pump may allow the patient to self-administer individual dosesof the medication on an as-needed basis.

SUMMARY

Systems, methods, and articles of manufacture, including computerprogram products, are provided for tracking medication delivered to apatient using a patient-controlled analgesic pump. For example, apatient-controlled analgesic pump may be communicatively coupled with atracking engine configured to track the volume of a medication deliveredto a patient over the administration of multiple doses and/or syringesof the medication.

According to some aspects, a method may include receiving, from a volumemeter at a pump, a first data indicative of a volume of a firstmedication present in a first syringe inserted in the pump. The pump maydeliver the first medication to a patient. The method may also includeupdating, based at least on the first data, a first counter in responseto the first medication being delivered to the patient from the firstsyringe as a first dose type or a second counter in response to thefirst medication being delivered to the patient from the first syringeas a second dose type. The method may further include determining, basedat least on the first counter and/or the second counter, a first volumeof the first medication delivered to the patient. The method may alsoinclude sending, to a mobile device, an electronic alert in response toone or more anomalies being present in the first volume of the firstmedication delivered to the patient.

In some aspects, the first volume includes a first individual volume ofthe first medication that is delivered to the patient as the first dosetype, a second individual volume of the first medication that isdelivered to the patient as the second dose type, and/or a total volumeof the first medication that is delivered to the patient as the firstdose type and the second dose type.

In some aspects, the method may also include receiving, from a tagreader at the pump, a second data identifying a second medication in asecond syringe that is inserted into the pump to replace the firstsyringe. The method may also include resetting the first counter and thesecond counter in response to the second medication being a differentmedication than the first medication included in the first syringe.

In some aspects, the method may also include updating the first counterin response to the second medication being delivered to the patient asthe first dose type and/or the second counter in response to the secondmedication being delivered to the patient as the second dose type.

In some aspects, the method may also include in response to the secondmedication being a same medication as the first medication, updating thefirst counter in response to the first medication being delivered to thepatient from the second syringe as the first dose type and/or the secondcounter in response to the first medication being delivered to thepatient from the second syringe as the second dose type.

In some aspects, the method may also include in response to the seconddata indicating that the second syringe is associated with a differentpatient than the first syringe, resetting the first counter and thesecond counter.

In some aspects, the tag reader may read a first identifier tagassociated with the first syringe and/or a second identifier tagassociated with the second syringe. The first identifier tag and/or thesecond identifier tag may include a barcode, a quick response (QR) code,and/or a radio frequency identification (RFID) tag.

In some aspects, the first dose type and the second dose type include adifferent one of a patient demand dose, a clinician dose, a loadingdose, and a maintenance dose.

In some aspects, the one or more anomalies include the first volumebeing greater than a maximum threshold value or less than a minimumthreshold value.

DETAILED DESCRIPTION

A patient-controlled analgesic pump may allow a patient to directlycontrol the delivery of a medication instead of having to rely onmedical professionals to administer the opioid pain medication viaintramuscular injections or intravenous injections. For example, thepatient-controlled analgesic pump may include a syringe containingmultiple doses of the medication, which may be administered to a patientas one or more patient demand doses, clinician doses, loading doses,and/or maintenance doses. Moreover, the patient may receive multiplesyringes of the medication during the course of treatment. Consequently,the actual volume of medication that is delivered to the patient may bedifficult to track, thereby giving rise to opportunities for medicationto be abused or diverted to third parties who are not legally authorizedto receive, possess, and/or consume the medication. As such, in someexample embodiments, a tracking engine may be configured to determinethe actual volume of medication delivered to a patient across multipledoses and/or syringes of the medication administered to the patient.Tracking the actual volume of medication delivered to the patient mayreduce and/or eliminate opportunities for abuse or diversion.

FIG. 1A depicts a system diagram illustrating a medication trackingsystem 100, in accordance with some example embodiments. Referring toFIG. 1A, the medication tracking system 100 may include a trackingengine 110, a pump 22, and a client 130. As FIG. 1A shows, the trackingengine 110, the pump 22, and/or the client 130 may be communicativelycoupled via a network 150. The client 130 may be a mobile device suchas, for example, a smartphone, a tablet computer, a wearable apparatus,and/or the like. However, it should be appreciated that the client 130may be any processor-based device including, for example, a desktopcomputer, a laptop computer, a workstation, and/or the like. Meanwhile,the network 150 may be any wired and/or wireless network including, forexample, a public land mobile network (PLMN), a local area network(LAN), a virtual local area network (VLAN), a wide area network (WAN),the Internet, and/or the like. Additionally and/or alternatively, thetracking engine 110 and/or the client 130 may form at least a part ofthe pump 22.

The pump 22 may be a patient-controlled analgesic (PCA) pump configuredto deliver a medication to a patient. However, it should be appreciatedthat the pump 22 may be any infusion system configured to deliver asubstance (e.g., fluid, nutrients, medication, and/or the like) to apatient's circulatory system or epidural space via, for example,intravenous infusion, subcutaneous infusion, arterial infusion, epiduralinfusion, and/or the like. Alternatively, the pump 22 may be an infusionsystem configured to deliver a substance (e.g., fluid, nutrients,medication, and/or the like) to a patient's digestive system via anasogastric tube (NG), a percutaneous endoscopic gastrostomy tube (PEG),nasojejunal tube (NJ), and/or the like. Moreover, the pump 22 may bepart of a patient care system that includes one or more additionalpumps.

As FIG. 1A shows, the pump 22 may be configured to receive one or moresyringes containing a medication such as, for example, a opioid painmedication (e.g., morphine, hydromorphone, fentanyl, and/or the like).For example, a first syringe 140 a containing a first medication may beinserted into the pump 22 such that the pump 22 may deliver the firstmedication to the patient in one or more doses including, for example,patient demand doses, clinician doses, loading doses, and/or maintenancedoses. The first syringe 140 a may be removed from the pump 22 andreplaced with a second syringe 140 b containing the first medication ora second medication, for example, when a threshold quantity of the firstmedication remains in the first syringe 140 a, when a threshold quantityof the first medication has been delivered to the patient from the firstsyringe 140 a, and/or the like.

In some example embodiments, the tracking engine 110 may be configuredto determine the volume of one or more medications delivered to apatient via the pump 22 across multiple syringes of the medicationincluding, for example, the first syringe 140 a, the second syringe 140b, and/or the like. For example, the tracking engine 110 may track thevolume of the first medication delivered to the patient in response tothe first syringe 140 a being inserted into the pump 22 and/or the firstmedication from the first syringe 140 a being delivered to the patient.Alternatively and/or additionally, the tracking engine 110 may track thevolume of the second medication delivered to the patient in response tothe second syringe 140 b being inserted into the pump 22 and/or thesecond medication from the second syringe 140 b being delivered to thepatient. To further illustrate, FIG. 2A depicts volume tracking acrossmultiple syringes of the same medication administered to the patient, inaccordance with some example embodiments. For example, the trackingengine 110 may track a volume of a medication delivered by a firstsyringe (e.g., the first syringe 140 a) and a second syringe (e.g., thesecond syringe 140 b) after the medication from the first syringe hasbeen delivered to the patient. As described in more detail below, thetracking engine 110 may report the tracked volume of medicationdelivered by each syringe to a device, such as a display having a userinterface of the client 130 and/or the pump 22 (see FIG. 4).

Furthermore, the tracking engine 110 may track the volume of the one ormore medications that is delivered to the patient from the first syringe140 a and/or the second syringe 140 b as different doses of medication.For instances, the tracking engine 110 may track the doses of the firstmedication and/or the second medication that are delivered to thepatient as patient demand doses, clinician doses, loading doses,maintenance doses, and/or the like. To further illustrate, FIG. 2Bdepicts volume tracking over multiple doses of the same medicationadministered to a patient, in accordance with some example embodiments.As described in more detail below, the tracking engine 110 may reportthe tracked volume of medication delivered by each syringe,corresponding to each type of dose, to a device, such as a displayhaving a user interface of the client 130 and/or the pump 22 (see FIG.4).

As used herein, a patient demand dose may refer to a single dose of themedication that the pump 22 delivers to the patient in response to arequest from the patient while a clinician dose may refer to a singledose of the medication that the pump 22 delivers to the patient inresponse to a request from a medical professional. Meanwhile, a loadingdose may refer a higher dose of the medication that the pump 22 deliversto the patient at a start of a treatment whereas a maintenance dose mayrefer to a lower dose of the medication that the pump 22 delivers to thepatient subsequent to one or more loading doses. Maintenance doses ofthe medication may be delivered to the patient, for example, in fixedsize portions and/or at a set rate.

In some example embodiments, the tracking engine 110 may respond to asyringe of medication being inserted into the pump by at leastidentifying the medication contained in the syringe. For example, thetracking engine 110 may respond to the first syringe 140 a beinginserted into the pump 22 by at least identifying the medication that iscontained in the first syringe 140 a. Alternatively and/or additionally,the tracking engine 110 may respond to the second syringe 140 b beinginserted into the pump 22, for example, to replace the first syringe 140a, by at least identifying the medication contained in the secondsyringe 140 b. If the tracking engine 110 determines that the secondsyringe 140 b contains the same first medication as the first syringe140 a, the tracking engine 110 may continue to track the volume of thefirst medication that is being delivered to the patient from the secondsyringe 140 b. By contrast, if the tracking engine 110 determines thatthe second syringe 140 b contains the second medication instead of thefirst medication contained in the first syringe 140 a, the trackingengine 110 may begin tracking the volume of the second medication thatis being delivered to the patient from the second syringe 140 b.

As FIG. 1A shows, the pump 22 may include a tag reader 122 configured toread a first identifier tag 145 a associated with the first syringe 140a and/or a second identifier tag 145 b associated with the secondsyringe 140 b. For example, the first identifier tag 145 a and/or thesecond identifier tag 145 b may be a barcode, a quick response (QR)code, a radio frequency identification (RFID) tag, and/or the like. Insome example embodiments, the first identifier tag 145 a and/or thesecond identifier tag 145 b may store data identifying the medicationcontained in the first syringe 140 a and/or the second syringe 140 b.Alternatively and/or additionally, the first identifier tag 145 a and/orthe second identifier tag 145 b may store data identifying the patient,the medical professional, the compounding facility, and/or the treatmentfacility associated with the first syringe 140 a and/or the secondsyringe 140 b. Accordingly, the tracking engine 110 may identify, basedon an output from the tag reader 122 at the pump 22, the medication, thepatient, the medical professional, the compounding facility, and/or thetreatment facility associated with each of the first syringe 140 aand/or the second syringe 140 b.

In some example embodiments, the tracking engine 110 may maintain one ormore counters in order to track the volume of a medication delivered tothe patient across multiple doses including, for example, patient demanddoses, clinician doses, loading doses, and/or maintenance doses.Referring again to FIG. 1A, the tracking engine 110 may maintain aplurality of counters, each of which being configured to track thevolume of a medication that is delivered to a patient as a correspondingdosage type. For instance, the tracking engine 110 may maintain a firstdose counter 115 a configured to track the volume of the medicationdelivered as one or more maintenance doses and a second dose counter 115b configured to track the volume of the medication delivered as one ormore patient demand doses. The tracking engine 110 may update the firstdose counter 115 a and/or the second dose counter 115 b based on anoutput from a volumetric device such as a volume meter 124 at orcommunicatively coupled with the pump 22.

The volume meter 124 may be configured to report, to the tracking engine110, a volume of medication in the first syringe 140 a and/or the secondsyringe 140 b in response to one or more events including, for example,the insertion of a syringe, the administration of one or more doses ofmedication, and/or the like. The first dose counter 115 a and/or thesecond dose counter 115 b may be updated based at least on the volume ofmedication delivered from the first syringe 140 a and/or the secondsyringe 140 b reported by the volume meter 124. For instance, the volumemeter 124 may report, to the tracking engine 110, an initial volume ofthe medication present in the first syringe 140 a and/or the secondsyringe 140 b when the first syringe 140 a and/or the second syringe 140b is first inserted into the pump 22. Alternatively and/or additionally,the volume meter 124 may report, to the tracking engine 110, the volumeof medication delivered from the first syringe 140 a and/or the secondsyringe 140 b after the administration of each dose of the medication.For example, the volume meter 124 may report, to the tracking engine110, the volume of medication delivered by the first syringe 140 aand/or the second syringe 140 b after the administration of a patientdemand dose, a clinician dose, a loading dose, and/or a maintenancedose. To determine an initial volume in a syringe, the volume meter 124may receive programming information for the infusion such as a totalvolume to be infused. In some implementations, the volume meter 124 mayuse images to detect an identifier on the syringe or a level ofmedication within the syringe. Based on analysis of one or more images,the volume may be determined. The analysis may include identifying afluid level within the syringe, identifying a marking on the syringe(e.g., volumetric graduation markings, structural references, scannablecodes), or other detectable features. For example, if a fluid line maybe identified at a particular volume marking thereby providing a volumewithin the syringe. As another example, the image may show informationidentifying the syringe such as a barcode or serial number. Thisinformation may be used to query a database to identify the volume ofmedication included by the preparer of the syringe (e.g., pharmacy,prescribing physician). In some implementations, the information mayidentify the geometry of the syringe which may then be used to generatea volume for the syringe.

The volume meter 124 may track specific volume of medication delivered.In some implementations, the volume meter 124 may provide an estimatedvolume delivered. The estimate may generated based at least in part onone or more of a flow rate, volume to be infused (“VTBI”), and durationof the infusion.

As noted, the tracking engine 110 may determine, based at least on avalue of one or more counters maintained by the tracking engine 110, thevolume of the first medication and/or the second medication delivered tothe patient via the pump 22. For example, the tracking engine 110 maymaintain the first dose counter 115 a and/or the second dose counter 115b by at least storing a current value of the first dose counter 115 aand/or the second dose counter 115 b. Furthermore, the tracking engine110 may update the current value of the first dose counter 115 a and/orthe second dose counter 115 b to reflect the volume of a medicationdelivered to the patient as one or more maintenance doses and/or patientdemand doses from the first syringe 140 a, which contains the firstmedication. For example, the tracking engine 110 may increment thecurrent value of the first dose counter 115 and/or the second dosecounter 115 b when one or more maintenance doses and/or patient demanddoses are delivered to the patient from the first syringe 140 a.

In some example embodiments, the tracking engine 110 may reset the firstdose counter 115 a and/or the second dose counter 115 b when the firstsyringe 140 a containing the first medication is replaced with thesecond syringe 140 b containing the second medication. For instance,when the tracking engine 110 determines that the second syringe 140 bcontains the second medication instead of the first medication containedin the first syringe 140 a, the tracking engine 110 may reset the firstdose counter 115 a and the second dose counter 115 b by at least settingthe current value of the first dose counter 115 a and the second dosecounter 115 b to zero. The first dose counter 115 a and the second dosecounter 115 b may be reset in order to avoid conflating the volume ofthe first medication that is delivered to the patient from the firstsyringe 140 a with the volume of the second medication that is deliveredto the patient from the second syringe 140 b.

Alternatively and/or additionally, the tracking engine 110 may reset thefirst dose counter 115 a and/or the second dose counter 115 b inresponse to the patient being disassociated with the pump 22 and/or adifferent patient being associated with the pump 22. For example, thetracking engine 110 may set the current value of the first dose counter115 and the second dose counter 115 b to zero when the tracking engine110 determines that the patient is disassociated with the pump 22 and/ora different patient is associated with the pump 22. The first dosecounter 115 a and the second dose counter 115 b may be reset in thiscase in order to avoid conflating the volume of medication delivered todifferent patients.

In some example embodiments, the tracking engine 110 may be configuredto generate one or more electronic alerts based on the volume ofmedication delivered to the patient across multiple doses and/orsyringes. For example, the tracking engine 110 may generate the one ormore electronic alerts in response to the volume of medication deliveredto the patient being greater and/or less than a threshold value. The oneor more electronic alerts may include wireless alert messages such as,for example, push notifications, short messaging service (SMS) message,and/or the like. Furthermore, the one or more electronic alerts mayinclude an indication of the type of anomaly including, for example, thevolume of medication delivered being greater than a threshold value, thevolume of medication delivered being less than a threshold value, and/orthe like. Alternatively and/or additionally, the one or more electronicalerts may include a patient identifier, a medication identifier, and/ora quantity of medication delivered to the patient. For instance, the oneor more electronic alerts may specify the volume of medication, thequantity of doses, and/or the type of doses (e.g., patient demand doses,clinician doses, loading doses, maintenance doses, and/or the like)delivered to the patient.

For example, the tracking engine 110 may detect the presence of one ormore anomalies in the volume of a medication delivered to the patientfrom the first syringe 140 a and/or the second syringe 140 b.Alternatively and/or additionally, the tracking engine 110 may detectthe presence of one or more anomalies in the volume of the medicationdelivered to the patient as one or more patient demand doses, cliniciandoses, loading doses, and/or maintenance doses. The one or moreanomalies may include the volume of medication delivered to the patientbeing greater and/or less than one or more threshold values. FIG. 3depicts examples of alert thresholds associated with the medicationtracking system 100, in accordance with some example embodiments. Inresponse to detecting the presence of the one or more anomalies, thetracking engine 110 may generate the one or more alerts, which may besent to a medical professional associated with the client 130.

FIG. 1B depicts a block diagram illustrating the medication trackingsystem 100, in accordance with some example embodiments. Referring toFIGS. 1A-B, the tracking engine 110 of the medication tracking system100 may be configured to maintain one or more counters including, forexample, the first dose counter 115 a, the second dose counter 115 b,and/or the like. The value of the first dose counter 115 a and/or thesecond dose counter 115 b may be updated by the tracking engine 110 inresponse to the medication from the first syringe 140 a beingadministered to the patient as one or more patient demand doses,clinician doses, loading doses, and/or maintenance doses. The trackingengine 110 may continue to update (e.g., increment) the first dosecounter 115 a and/or the second dose counter 115 b when the firstsyringe 140 a is replaced with the second syringe 140 b if the trackingengine 110 determines, based at least on the first identifier tag 145 aand/or the second identifier tag 145 b read by the tag reader 122 at thepump 22, that the second syringe 140 b is associated with at least thesame medication and patient as the first syringe 140 a.

Alternatively and/or additionally, FIG. 1B shows that the trackingengine 110 may be configured to reset the first dose counter 115 a andthe second dose counter 115 b to a specified starting value if thetracking engine 110 determines, based at least on the first identifiertag 145 a and/or the second identifier tag 145 b read by the tag reader122 at the pump 22, that the second syringe 140 b is associated with adifferent medication and/or patient as the first syringe 140 a. Forexample, if the tracking engine 110 determines that the second syringe140 b contains a different medication than the first syringe 140 a, thefirst dose counter 115 a and the second dose counter 115 b may be resetin order to avoid conflating the volume of different medicationsdelivered to the patient. Alternatively and/or additionally, if thetracking engine 110 determines that the second syringe 140 b isassociated with a different patient than the first syringe 140 a, thefirst dose counter 115 and the second dose counter 115 b may be reset inorder to avoid conflating the volume of medication delivered todifferent patients.

Furthermore, FIG. 1B shows that the tracking engine 110 may beconfigured to generate one or more alerts, which may be sent to amedical professional associated with the client 130. The tracking engine110 may generate the one or more alerts in response to the trackingengine 110 detecting the presence of one or more anomalies in the volumeof a medication delivered to the patient, for example, from the firstsyringe 140 a and/or the second syringe 140 b. As FIG. 3 furtherillustrates, the tracking engine 110 may generate the one or more alertsin response to anomalies that include the volume of medication deliveredto the patient being greater than a maximum threshold value and/or lessthan a minimum threshold value. The maximum threshold value and/or theminimum threshold value may be associated with a time interval such thatthe tracking engine 110 may generate the one or more alerts if anexcessive volume and/or an inadequate volume of medication is deliveredto the patient over the time interval (e.g., 24 hours and/or the like).For example, as shown in FIG. 2A, the tracking engine 110 may generatethe one or more alerts, such as an occlusion alarm, if an inadequatevolume of medication is delivered to the patient over a set timeinterval. In some embodiments, the volume of delivered medication isinadequate when a volume of the delivered medication is less than avolume of a desired dose of the medication and/or a volume of a syringe(e.g., the first syringe 140 a and/or the second syringe 140 b).

FIG. 4 depicts an example display including a user interface 300. Theuser interface 300 may form a part of the client 130 and/or the pump 22.The user interface 300 shows an example status summary of variousaspects of the delivery of medication via a first pump channel (e.g.,Channel A), which represents pump 22.

The user interface 300 may receive and display data received from thetracking engine 110 and/or flow meter 124. For example, the userinterface 300 may display a start time of medication delivery by eachsyringe (e.g., the first syringe 140 a, the second syringe 140 b, etc.)coupled with the pump 22, an end time of medication delivery by eachsyringe coupled with the pump 22, an average, current, and/or desireddelivery rate of medication delivered to the patient, the VTBI, a volumeof medication already infused to the patient by the coupled syringe, anda cumulative volume of medication delivered to the patient. As notedabove, the cumulative volume may be generated, at least in part, basedon one or more of a flow rate, the VTBI, a duration of the infusion, avalue of one or more counters maintained by the tracking engine 110, thevolume of the first medication and/or the second medication delivered tothe patient via the pump 22 and/or the like. The user interface 300 mayallow for and/or receive a selection of one or more time periods, suchas 1 hour, 12 hours, 48 hours, and/or other time intervals therebetween,of the cumulative volume.

Determining and displaying the cumulative volume over various timeperiods may help to ensure that the proper amount of medication has beendelivered to the patient, help to limit or prevent diversion of themedication, and/or may assist users when converting patients to anotherform of treatment, such as a tapering plan, a pill, and/or the like. Forexample, the user interface 300 may provide the user with informationabout the start time and end time of medication delivery from aparticular syringe, and the time at which a syringe is replaced. Theuser interface 300 may also display the cumulative volume of themedication delivered and the amount of medication left to be deliveredto the patient. Thus, via the user display 300, the user may easilydetermine whether a volume of medication has been improperly divertedfrom the pump 22. Additionally and/or alternatively, based on thedetermined and/or displayed cumulative volume, a user may change thecurrent treatment plan and/or taper the patient off of the medicationbeing delivered to the patient.

FIG. 5 depicts a flowchart illustrating a process 400 for tracking thevolume of a medication delivered to a patient, in accordance with someexample embodiments. Referring to FIG. 5, the process 400 may beperformed by the medication tracking system 100.

At 402, the medication tracking system 100 may track a first volume of afirst medication delivered to a patient from a first syringe inserted inthe pump 22 by at least maintaining a first counter that is updated inresponse to the first medication being administered to the patient as afirst dose type and a second counter that is updated in response to thefirst medication being administered to the patient as a second dosetype. For example, the tracking engine 110 may track the volume of thefirst medication delivered to the patient from the first syringe 140 ain the pump 22 by at least maintaining one or more counters including,for example, the first dose counter 115 a, the second dose counter 115b, and/or the like. Each of the counters may be associated with a dosetype that may be administered to the patient including, for example, apatient demand dose, a clinician dose, a loading dose, and/or amaintenance dose. As such, the value of each of the counters may beupdated in response to the medication in the first syringe 140 a beingdelivered to the patient as a corresponding dose type. For instance, thefirst dose counter 115 a may be updated whenever a maintenance dose ofthe first medication is administered to the patient from the firstsyringe 140 a while the second dose counter 115 b may be updatedwhenever a patient demand dose of the first medication is administeredto the patient from the first syringe 140 a.

At 404, the medication tracking system 100 may determine, based at leaston the first counter and/or the second counter, the first volume of thefirst medication delivered to the patient. For example, the trackingengine 110 may determine, based at least on the respective values of thefirst dose counter 115 a and the second dose counter 115 b, the volumeof the first medication that is administered to the patient asmaintenance doses, the volume of the first medication that isadministered to the patient as patient demand doses, and/or the totalvolume of the first medication that is administered to the patientacross all dose types.

At 406, the medication tracking system 100 may reset the first counterand the second counter in response to a second syringe containing asecond medication being inserted into the pump 22 to replace the firstsyringe. For example, the tracking engine 110 may reset the first dosecounter 115 a and the second dose counter 115 b when the second syringe140 b that is inserted into the pump 22 to replace the first syringe 140a contains a different medication than the first syringe 140 a.Alternatively and/or additionally, the first dose counter 115 a and thesecond dose counter 115 b may also be reset if the second syringe 140 bis associated with a different patient with the first syringe 140 a. Inthe event that the second syringe 140 b contains the same medication andis associated with the same patient as the first syringe 140 a, thetracking engine 110 may continue updating the first dose counter 115 aand/or the second dose counter 115 b without resetting the first dosecounter 115 a and/or the second dose counter 115 b. The first dosecounter 115 a may be updated in response to the first medication beingadministered to the patient from the second syringe 140 b as amaintenance dose while the second dose counter 115 b may be updated inresponse to the first medication being administered to the patient fromthe second syringe 140 b as a patient demand dose.

At 408, the medication tracking system 100 may track a second volume ofthe second medication delivered to a patient from the second syringeinserted in the pump 22 by at least updating the first counter inresponse to the second medication being administered to the patient asthe first dose type and/or the second counter in response to the secondmedication being administered to the patient as the second dose type.For example, the tracking engine 110 may begin tracking the volume ofthe second medication delivered to the patient from the second syringe140 b when the second syringe 140 b containing the second medication isinserted into the pump 22. The tracking engine 110 may track the volumeof the second medication delivered to the patient by at least updatingthe first dose counter 115 a whenever a maintenance dose of the secondmedication is administered to the patient from the second syringe 140 band the second dose counter 115 b whenever a patient demand dose of thesecond medication is administered to the patient from the second syringe140 b.

At 410, the medication tracking system 100 may determine, based at leaston the first counter and/or the second counter, the second volume of thesecond medication delivered to the patient. For example, the trackingengine 110 may determine, based at least on the respective values of thefirst dose counter 115 a and the second dose counter 115 b, the volumeof the second medication that is administered to the patient asmaintenance doses, the volume of the first medication that isadministered to the patient as patient demand doses, and/or the totalvolume of the first medication that is administered to the patientacross all dose types.

At 412, the medication tracking system 100 may generate and send, to theclient 130, an electronic alert in response to detecting one or moreanomalies in the first volume of the first medication delivered to thepatient and/or the second volume of the second medication delivered tothe patient. For example, the tracking engine 110 may detect one or moreanomalies that include the first volume of the first medicationdelivered to the patient and/or the second volume of the secondmedication delivered to the patient being greater, less than, or equalto a threshold value. The tracking engine 110 may additionally and/oralternatively detect one or more anomalies that include a detecteddiversion event, such as when a discrepancy exists between an amount ofmedication delivered to the patient and an amount of medication thatshould remain to be delivered to the patient. The tracking engine 110may generate an electronic alert that includes, for example, a wirelessalert message such as, for example, a push notification, a shortmessaging service (SMS) message, and/or the like. The electronic alertmay be sent to the client 130, which may be associated with a medicalprofessional.

In some example embodiments, the pump 22 may be part of a patient caresystem 20 shown in FIG. 7A. Referring to FIG. 7A, the patient caresystem 20 may include the pump 22 as well as additional pumps 24, 26,and 28. As shown in FIG. 7A, each of the pump 22, 24, 26, and 28 may befluidly connected with an upstream fluid line 30, 32, 34, and 36,respectively. Moreover, each of the four pumps 22, 24, 26, and 28 mayalso fluidly connected with a downstream fluid line 31, 33, 35, and 37,respectively. The fluid lines can be any type of fluid conduit, such astubing, through which fluid can flow. At least a portion of one or moreof the fluid lines may be constructed with a multi-layered configurationas described herein.

Fluid supplies 38, 40, 42, and 44, which may take various forms but inthis case are shown as bottles, are inverted and suspended above thepumps. Fluid supplies may also take the form of bags, syringes, or othertypes of containers. Both the patient care system 20 and the fluidsupplies 38, 40, 42, and 44 are mounted to a roller stand or intravenous(IV) pole 46.

A separate pump 22, 24, 26, and 28 may be used to infuse each of thefluids of the fluid supplies into the patient. The pumps 22, 24, 26, and28 may be flow control devices that will act on the respective fluidline to move the fluid from the fluid supply through the fluid line tothe patient 48. Because individual pumps are used, each can beindividually set to the pumping or operating parameters required forinfusing the particular medical fluid from the respective fluid supplyinto the patient at the particular rate prescribed for that fluid by thephysician. Such medical fluids may comprise drugs or nutrients or otherfluids.

Typically, medical fluid administration sets have more parts than areshown in FIG. 7A. Many have check valves, drip chambers, valved ports,connectors, and other devices well known to those skilled in the art.These other devices have not been included in the drawings so as topreserve clarity of illustration. In addition, it should be noted thatthe drawing of FIG. 7A is not to scale and that distances have beencompressed for the purpose of clarity. In an actual setting, thedistance between the bottles 38, 40, 42, and 44 and the pump modules 22,24, 26, and 28 could be much greater.

Referring now to FIG. 7B, an enlarged view of the front of the patientcare system 20 is shown. The pump 22 may include a front door 50 and ahandle 52 that operates to lock the door in a closed position foroperation and to unlock and open the door for access to the internalpumping and sensing mechanisms and to load administration sets for thepump. When the door is open, the tube can be connected with the pump, aswill be shown in FIG. 7C. When the door is closed, the tube is broughtinto operating engagement with the pumping mechanism, the upstream anddownstream pressure sensors, and the other equipment of the pump. Adisplay 54, such as an LED display, is located in plain view on the doorin this embodiment and may be used to visually communicate variousinformation relevant to the pump, such as alert indications (e.g., alarmmessages). Control keys 56 exist for programming and controllingoperations of the pump as desired. The pump 22 also includes audio alarmequipment in the form of a speaker (not shown).

In the embodiment shown, a programming module 60 is attached to the leftside of the pump 22. Other devices or modules, including another pump,may be attached to the right side of the pump 22, as shown in FIG. 7A.In such a system, each attached pump represents a pump channel of theoverall patient care system 20. In one embodiment, the programmingmodule is used to provide an interface between the pump 22 and externaldevices as well as to provide most of the operator interface for thepump 22.

The programming module 60 includes a display 62 (which may include theuser interface 300) for visually communicating various information, suchas the operating parameters of the pump 22 and alert indications andalarm messages. The programming module 60 may also include a speaker toprovide audible alarms. The programming module or any other module alsohas various input devices in this embodiment, including control keys 64and a bar code or other scanner or reader for scanning information froman electronic data tag relating to the infusion, the patient, the caregiver, or other. The programming module also has a communications system(not shown) with which it may communicate with external equipment suchas a medical facility server or other computer and with a portableprocessor, such as a handheld portable digital assistant (“PDA), or alaptop-type of computer, or other information device that a care givermay have to transfer information as well as to download drug librariesto a programming module or pump. In some implementations, the pump 22may provide volume data to the programming module 60, which, in turn,may maintain the counters and/or cause transmission of alert messagesassociated with detected anomalies. In such implementations, theprogramming module 60 may communicate with the tracking engine 110,include the tracking engine 110, or implement features of the trackingengine 110 described herein.

The communications system may take the form of a radio frequency (“RF”)(radio frequency) system, an optical system such as infrared, a BlueTooth system, or other wired or wireless system. The bar code scannerand communications system may alternatively be included integrally withthe pump 22, such as in cases where a programming module is not used, orin addition to one with the programming module. Further, informationinput devices need not be hard-wired to medical instruments, informationmay be transferred through a wireless connection as well.

FIG. 7B includes a second pump 26 connected to the programming module60. As shown in FIG. 7A, more pump modules may be connected.Additionally, other types of modules may be connected to the pumpmodules or to the programming module. In such implementations, thetracking engine 110 may maintain respective dose type counters for eachpump (e.g., pump 22 and pump 26).

Turning now to FIG. 7C, the pump 22 is shown in perspective view withthe front door 50 open, showing the upstream fluid line 30 anddownstream fluid line 31 in operative engagement with the pump 22. Thepump 22 directly acts on a tube 66 (also referred to as a pump segment)that connects the upstream fluid line 30 to the downstream fluid line 31to form a continuous fluid conduit, extending from the respective fluidsupply 38 (FIG. 7A) to the patient 48, through which fluid is acted uponby the pump to move fluid downstream to the patient. Specifically, apumping mechanism 70 acts as the flow control device of the pump to movefluid though the conduit. The upstream and downstream fluid lines and/ortube 66 may be coupled to a pump cassette or cartridge that isconfigured to be coupled to the pump 22, such as the type described inco-pending U.S. patent application Ser. No. 13/827,775, which isincorporated by reference herein.

The type of pumping mechanism may vary and may be for example, amultiple finger pumping mechanism. For example, the pumping mechanismmay be of the “four finger” type and includes an upstream occludingfinger 72, a primary pumping finger 74, a downstream occluding finger76, and a secondary pumping finger 78. The “four finger” pumpingmechanism and mechanisms used in other linear peristaltic pumps operateby sequentially pressing on a segment of the fluid conduit by means ofthe cam-following pumping fingers and valve fingers 72, 74, 76, and 78.The pressure is applied in sequential locations of the conduit,beginning at the upstream end of the pumping mechanism and workingtoward the downstream end. At least one finger is always pressing hardenough to occlude the conduit. As a practical matter, one finger doesnot retract from occluding the tubing until the next one in sequence hasalready occluded the tubing; thus at no time is there a direct fluidpath from the fluid supply to the patient. The operation of peristalticpumps including four finger pumps is well known to those skilled in theart and no further operational details are provided here.

In this particular embodiment, FIG. 7C further shows a downstreampressure sensor 82 included in the pump 22 at a downstream location withrespect to the pumping mechanism. The downstream pressure sensor 82 ismounted to the flow control device 70 and is located adjacent anddownstream in relation to the flow control device. The downstreampressure sensor is located downstream from the flow control device, thatis, at a location between the patient 48 (FIG. 7A) and the flow controldevice, so that the connection of the correct fluid supply with thecorrect pump may be verified before any fluid is pumped to the patient.

With reference still to FIG. 7C, an upstream pressure sensor 80 may alsobe included in the pump 22. The upstream pressure sensor is assigned tothe flow control device or pumping mechanism 70 and, in this embodiment,is further provided as an integral part of the pump 22. It is mounted tothe flow control device 70 and is located adjacent and upstream inrelation to the flow control device. The upstream pressure sensor islocated upstream from the flow control device, that is, at a locationbetween the fluid supply 38 (FIG. 7A) and the flow control device, sothat the connection of the correct fluid supply with the correct pumpmay be verified before any fluid is pumped to the patient. In animplementation where the source is a syringe, the flow control device 70may be configured to press a plunger of the syringe to provide theinfusion according to the programmed parameters.
